To me ssse3 looks too close to sse3 to add an option like that.  People
are going to be confused.

Also you need to add to the sentence after the options about SSSE3 (and
SSE3):

Actually I think this part of the document needs a rewrite now since
there are no too many options together and adding more is going to make
this look silly.

Also you forgot to update "X86 Built-in Functions" Section in the
document which needs some love right now since it is not up to date and
still references old non existent functions.
